使用相同 class Jquery UI 范围滑块的问题

Question

我多次使用具有相同 class 的 Jquery UI Range Slider，这是我在代码段中添加的，它会完美运行，但数据值不显示第二个滑块.

它是在更改滑块后显示的，而不是在 intilize 时显示的，所以请指导我在应用多范围滑块时做错了什么

$(document).ready(function() {
  var initialValues = [540, 1020],
    updateValue = function(ui) {
      var hours = Math.floor(ui.value / 60);
      var minutes = ui.value - (hours * 60);

      if (hours.length == 1) hours = '0' + hours;
      if (minutes.length == 1) minutes = '0' + minutes;
      if (minutes == 0) minutes = '00';
      if (hours >= 12) {
        if (hours == 12) {
          hours = hours;
          minutes = minutes + " PM";
        } else {
          hours = hours - 12;
          minutes = minutes + " PM";
        }
      } else {
        hours = hours;
        minutes = minutes + " AM";
      }
      if (hours == 0) {
        hours = 12;
        minutes = minutes;
      }
      $(ui.handle).attr('data-value', hours + ':' + minutes);
    };

  $(".slider-range").slider({
    min: 0,
    max: 1440,
    step: 15,
    range: true,
    values: [540, 1020],
    create: function(event, ui) {
      $.each(initialValues, function(i, v) {
        updateValue({
          value: v,
          handle: $('.ui-slider-handle').eq(i)
        });
      });
    },

您需要先找到要创建的 .slider-range 滑块，然后在其中搜索 .ui-slider-handle。
你可以用 .index() 找到哪一个： $(".slider-range").index(this)

$(document).ready(function() {
  var initialValues = [540, 1020],
    updateValue = function(ui) {
      var hours = Math.floor(ui.value / 60);
      var minutes = ui.value - (hours * 60);

      if (hours.length == 1) hours = '0' + hours;
      if (minutes.length == 1) minutes = '0' + minutes;
      if (minutes == 0) minutes = '00';
      if (hours >= 12) {
        if (hours == 12) {
          hours = hours;
          minutes = minutes + " PM";
        } else {
          hours = hours - 12;
          minutes = minutes + " PM";
        }
      } else {
        hours = hours;
        minutes = minutes + " AM";
      }
      if (hours == 0) {
        hours = 12;
        minutes = minutes;
      }
      
      $(ui.handle).attr('data-value', hours + ':' + minutes);
    };

  $(".slider-range").slider({
    min: 0,
    max: 1440,
    step: 15,
    range: true,
    values: [540, 1020],
    create: function(event, ui) {
      var index = $(".slider-range").index(this);
      $.each(initialValues, function(i, v) {
        updateValue({
          value: v,
          handle: $('.slider-range').eq(index).find('.ui-slider-handle').eq(i)
        });
      });
    },
    slide: function(event, ui) {
      updateValue(ui);
    }
  });
